How did World War I change in favour of the Allies in 1917?

Answer 1

The entry of the United States into the war on April 6th 1917 greatly increased the numbers of allied troops.

This was a breath of fresh air for France and Britain who were suffering,as was Germany and the Central Powers,from attrition running low on resources especially the most important one : MEN.

Although the U.S. had no major army to speak of prior to it's entry into the war.General John J."Black Jack" Pershing would quikly organise and train an army that would become four million strong by the end of the war.

Pershing was under tremendous pressure form both France and Britain to incorporate the U.S. troops into the French or British armies.

Pershing,however,refused to be coerced into letting his newly formed army be used mearly as replacements for lost French or British troops.

Pershings American Expedtionary Force would fight as a seperate army,although some forces of the Big Red One would fight as part of French units in 1917 to show Americas commitment to battle.

When General Ludendorf launced the "Kaiserslacht" in the spring of 1918 he used troops,that had been recently made available for use on the western front when Russia surrendered and the fighting ceased on the eastern front,to make a last ditch attempt to break the allied lines and win the war outright.

When this attempt failed and Germany and support for the war was running out in Germany,the promise of virtually unlimited troops from the U.S. made continueing the war a very difficult task for Germany.

Although the U.S. troops were "green" their numbers combined with the allied change in mass use of tanks in battle,like that of Cambrai and Amiens,along with attrition and political unrest and starvation in the homeland eventually forced Germany to sue for peace.

Answer 2

The British and French had been engaged with the Germans and Austrian troops in trench warfare since 1914. Both sides were worn by the engagement. In 1917, after the sinking of the Lusitania with loss of American lives( good excuse) the United States entered the fray, bringing many troops and new equipment thereby strengthening the Allied position. A little over a year later the war ended.

Answer 3

The won the battle of Vimy Ridge. The Amercains entered the war.

Answer 4

It was the American entrance into the war.

I'd like to say that it was because both my grandfathers arrived and all the Allies needed to win was two more Irishmen, but I thought it might sound like bragging.
